Judges 3:19-22

19But he himself turned back at the idols near Gilgal and said, "I have a secret message for you, O king." And he commanded, "Silence." And all his attendants went out from his presence.

20And Ehud came to him as he was sitting alone in his cool roof chamber. And Ehud said, "I have a message from God for you." And he arose from his seat.

21And Ehud reached with his left hand, took the sword from his right thigh, and thrust it into his belly.

22And the hilt also went in after the blade, and the fat closed over the blade, for he did not pull the sword out of his belly; and the dung came out.
